Things You'll Need
4 AA Batteries
Electronic digital safes can keep your valuables behind a numerical lock to protect them from burglary and fire. These safes work on the same principle as dial combination locks do, but make it easier to enter a code. Electronic digital safes come in all shapes and sizes, from large industrial safes to small portable safes.
Opening the Safe
Enter your code on the keypad located on the front of the safe. Some electronic digital safes require you to input a special character like "#" before and after your code. The safe should either beep, have a LED turn green, or display "OPEN" if you have correctly entered the code.
Turn the handle to the right within five seconds of correctly entering the code. If you wait too long, the safe will lock and you will have to enter your code again.
Open the safe with a key. Use your emergency key that came with the safe to open it if you forgot the code or if the batteries have died. Remove the key cover from either the handle or the control panel to reveal the lock.
Changing the Codes
Enter your code to open the safe.
Place the electronic digital safe into code reset mode. On some models you need to hold the last digit of the code or press the "*" button to get into code reset mode. Other safes require you to open them and press a small red button on the inside of the door.
Enter your new code on the keypad and press "#" to finish. Some safes may require you to press "*" or a letter to finish the code. If the safe requires it, enter the new code again to confirm that you entered it correctly.
Replacing the Battery
Use your code to open the electronic digital safe's door.
Locate and remove the battery cover on the inside of the door.
Replace the used batteries with new ones. For most safes, this will require two or four AA batteries.
Test the batteries. Use your code while the door is open to test the batteries before closing the safe.
